Often, printer owners are faced with one of the very common problems and then try to figure out and understand why the Canon printer does not scan at all or has stopped scanning now. Cause similar problem it can be very different, for example, sometimes it lies in the printer, or the printer is in order, and all because of the personal computer, because either a driver error or the printer was not connected to the computer quite accurately. In order for us to be able to find the cause of the problem and figure out why on this moment our scanner does not work, we just need to consider a few of the most logical reasons, and after we find them, we need to try programmatically eliminate them. First you need to make sure that installed scanner is currently in a stable working condition, and then you need to check it by connecting it to another personal computer. If these did not help, then The best decision, of course, what you turn to the services of service centers.
Now we will consider the most possible causes, we will also talk about methods that will help to eliminate them. So what should you do when the printer stops scanning?
Why Canon Scanner Doesn't Work
To understand why the Canon printer does not scan, first of all, pay attention to the computer, which, along with the printer, must be turned off, and then unplug the power cable from both devices. Wait about a minute, and after connecting the power again, turn on both devices. Doing so will clear the memory of your computer and the All-In-One, allowing the MFP to operate normally.
But if the scan did not start, and the previously working multifunctional device began to issue various error codes, then be sure to eliminate them in a timely manner. Find them detailed descriptions See the instructions that came with your printer. In addition, a multifunctional device of almost any model makes it possible to scan and copy in the so-called. service mode. To start it, first of all, turn off the device itself. Then press "Reset" and "Power" button. Then release the first button and press it twice (to different models the number of such clicks may be different - read more in the operating instructions of the device). At the end, release "Power" and check if the printer has become responsive to scanning commands.
Why can't my Canon printer scan?
If the printer does not scan and the above recommendations did not help you, be sure to try reconnecting the USB cable. Pull it out and plug it into another port on the PC. It is desirable to organize similar connection not through a USB hub, but directly to a personal computer. Then, first of all, check whether the PC has begun to see the printer connected to it. If the printer has become visible to the computer, then try scanning and printing a couple of sheets.
Another reason for the printer to print but not scan is scanner drivers that the user simply forgot to install. The question arises, what to do in this situation? So, if the PC does not see the scanner for this very reason, then download the appropriate drivers from our website or from the website of the manufacturer of your office equipment and install it. If you do not know what to download specifically, then it is better to download the full device driver. In addition, the reason may even lie in the installed driver, which simply “flew. In such a situation, you will have to uninstall it first and install the updated version.
Scans another device - a scanner. It is he who can convert into electronic format (digitize) various images, documents and other things.
Another thing is when the scanner and printer are combined in one device. In this case, the question is quite justified (we will lower our eyes to the curvature of the wording)
Canon printer not scanning, what should I do?
Everything is very individual, so I won’t talk about the reasons without seeing the patient. Here are a couple of general tips that might help.
Replacing the cable with a shorter one
In some cases, changing the USB cable to a shorter one saves. The trick is that some peripherals may not work correctly when the cable length is more than 1.5m. Some devices work, while others fail. Technology, in a word.
Installing the latest drivers
Any brand of printer has its own official website where you can download the latest drivers. Sometimes the drivers that came with the purchase become obsolete (for example, when the user changes the OS) and stop working, new ones are needed.
Proper setup and connection
Do everything according to the instructions, do not forget to make the printer the “default printer” (go through the control panel and change it)
Incorrectly flashed cartridge
Printing problem? If difficulties arose after refilling the cartridge, then it is incorrectly stitched.
Clear the "print queue"
The fact is that for combined devices (printer-scanner-copier), the simultaneous execution of functions can be technically impossible. Those. it will not be able to print and scan at the same time.
Often, office equipment users are faced with the need to find the answer to the question of why the printer does not scan. The cause of the problem may lie both in the MFP / printer and personal computer, and in the connection between them. To find the source of the problem and determine why the scanner is not working, you need to look at several possible causes and try to fix them. If you are sure that the device scanner is in working condition, then check it by connecting it to another PC. If nothing helps, then, of course, you will have to resort to the services of a service center.

In the event that the MFP prints but does not scan, you will have to reset its settings. Also this method will help in solving the following problems: the printer does not copy, stopped responding to user commands. You should reset the settings from the device menu or using special software.
In addition, the device may stop scanning due to a power supply failure - most models are connected to the mains using a similar part, as well as Cell phones. You can solve the problem by purchasing and installing a power supply with similar characteristics.
In general, situations are not uncommon when the printer works, but the MFP scanner does not function. Especially such a problem takes the user by surprise when a normally printing printer still fails. According to some experts, the MFP scanner may stop functioning due to the creation of microwaves by any objects. Therefore, before using the device for printing, it would be a good idea to turn off the microwave oven - perhaps this will help you.
In addition, if the printer is working but the scanner itself is not, then check the wiring grounding, mains voltage, and carefully inspect the wire connecting the PC to the scanner for visible damage.
There are a lot of reviews on the Internet and a lot of questions, in the manner of "Scanner does not scan, help!" or “I bought a new printer and the scanner doesn't work. What to do??!”, a lot of information on repairing or eliminating “symptoms of the disease”. Experts say that in 30% of cases, a completely serviceable car “falls ill”. So you do not need to immediately run to the service center and give the printer for repair. You can do the repair yourself.
For example, try a pre-scan, that is, run any software, which will get the image.
When the scan starts, it starts earlier installed driver. If the driver has not been installed, then you need to take installation disk that comes with the kit, and just install the one you need. If the driver is installed and ready to work, then the actions are completely different.
So, the software is there, but the device is not detected. The first step to start diagnosing the problem is by clicking on the Start panel, Find and go to Control Panel. Then find the item Administration, click on it. A window opens with a list of different functions. You need to find and launch the device manager (the light version is to go to the My Computer shortcut, click right click from scratch, and go to the equipment tab).
The item is found and another window pops up on the monitor, with a bunch of pluses and names. You need to find exactly the scanner and determine if it is installed. Searching for "Imaging Devices" shouldn't take long. So, click on the plus sign and here it is, the name of the model and next to it Exclamation point on a yellow background. What does it mean? This means that the drivers are either not suitable or outdated. But the way out is the same. We go to the Internet and find the driver we need.
You can also download a program that will automatically update all the drivers on the hardware. Drivers found and installed, restart the machine, you're done.
But what to do if everything is in working order in the device manager? The scanner is defined, but still refuses to work? There is one more snag. For normal functioning you need to purchase a specific program on the manufacturer's website. And, of course, not for a small amount. But this problem is also solved in the same way, you need to go online and find the right software.
Very often they ask this question, why, with a working device, the iron refuses to scan? Some solutions to this problem.
If the device uses a USB interface, then the connection port may be the reason and installation on a different port will solve all problems.
Still does not work, although everything has already been checked?
An important role is played by the operating system installed on a computer or laptop. Most manufacturers have recently released printers, and scanners are designed for use in the operating room. Windows system 7.
The easiest method to check is to open the "device manager" and check the controller, it should not be marked with a yellow exclamation mark. The controller should work optimally. If the problem arose, then you should try installing the scanner on another computer, perhaps the problem is with your hardware. It often happens that perfectly serviceable systems simply refuse to work. A striking example is the Mustek scanner, which simply refuses to work with Tekram's bus controllers. So before installing the scanner, you should definitely consult which bus it works on. this product or ask for advice on choosing a new controller.
If none of the proposed options fit and the scanner refuses to work further, then there is only one way out: carry it to a service center for warranty service. IN service center they will definitely help you and explain what the reason was.
